Jitter

Jitter when applied to VoIP is a variation in packet transit delay. The causes of jitter are typically queuing, contention and serialization effects on the path through the network. Faster, higher bandwidth networks tend to have less jitter whereas slower networks tend to have more congestion and more jitter. A QoS device like an ATA can help eliminate some of this jitter.
